Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) ordered that the animal slaughtered by a boy be eaten: "When he slaughters it saying the takbir, it should be eaten." (b) Mujahid (may Allah have mercy on him) said: There is no harm in eating the slaughtered animal of a child, of a woman, and of the People of the Book.
